Letters Patent No. 109,039, dated November 8, 1270 IMPROVEMENT IN sen-me BOILERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern: 7

Be it knownthat I, OHAnLns Natures, of New Orleans, in the parish of Orleans and' State oFLonisiana, have invented anew and useful Improvement in Setting Boilersfand I do hereby declare that the following is a fail, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

My invention relates to flue-boilers, and my object is to insure a temperature of from 800 to 1000 Fahrenheit in the combustion-6iiamber, to ignite the coalgascs effectual] y.

To accomplish this purpose, I iuterpose between the boiler, whose temperature never rises above 350, or thereabout, and the avenue through which the air reaches the combustion-clnumber, a downwardly-projecting arch.

By this means the requisite degree of heat to burn the gases may be obtained iii. half an hour, after much there will be no smoke.

Figure 1 is a iongitudirial section of the bricksetting of a boiler arranged according to my invention.

Figure 2 is atransverse section taken on the line a: a: of fig. 1;

Figure 3 is a section on the line 9 y of fig. 1; and

Figure 4 is a section on the line 2 offig. 1.

Similar letters of reference indicate corresponding parts, i

A is the bridge-m ll at the rear of the fire place, and i bridge A, near the termination-of the sloping side l down which the product of combustion in the fire-place is caused to pass on the way to the chamber B, so that the combination 'oi' the. air and the gases is efi'coted as soon as they enter the cfhnmber.

G represents the arch ahoye and behind the bridgewall A. This is built up against the boiler so to protect it from the contact of the gases where they commonly come in coniiact with it, and it slopes downward at the rear, to cause them to mix with the air in the chamber B, where they'are burned most completely, and the heat given up to the boiler beyond.

Having thus describediny invention,

I claim as new and desire to secure by Letters Patent r 1 The bridge-wall A, sloped at F, and having airpassage therethrough lirom under the grate, combined with a downwardly-sloped arch, G, fitting against .the

independent chamber, 1, wherein the air and gases are brought into contact, before passing up the smoke-pipe. v
